Futaba FUBS0169 Heavy Duty Aluminum Clamp Servo Horn (10-gram)  [FUBS0169]

Aluminum clamp-style horn for Futaba servos

The Futaba FUBS0169 clamp servo horn is a 10-gram aluminum accessory intended to replace standard plastic horns when increased stiffness and longer service life are needed for steering and control linkages.

The clamp wraps around the servo output to form a secure interface that reduces play compared with many push-on horns. Use this part where firmer steering response and stable link geometry matter, such as on high-precision on-road cars or scale models fitted with metal linkages.

Installation notes: set the servo to neutral, align the horn spline, slide the clamp onto the output, and tighten the clamp screws evenly to avoid shifting the horn angle. Use the correct hex driver and check for binding across the full travel before final trim adjustments. Because the aluminum horn is heavier than plastic, re-check end points and trims after fitting.

Tuning role: this heavy-duty clamp horn helps maintain linkage geometry under higher steering loads, which can produce crisper inputs and reduce slop from worn plastic horns. For best results, combine the horn with correctly adjusted turnbuckles or ball links and verify servo centring to preserve predictable steering geometry.

Select this clamp-style aluminum horn when you want a durable metal replacement that helps keep steering geometry tight in demanding RC setups.
